2021+ F-150 Whelen IONS mounting on/around running boards - Help

[WildfireSupt]

Does anyone have any mounting ideas on how to install regular Whelen IONS (non-surface mount) to running boards for low profile look? I’m looking to have it added to a 2021+ Ford F-150’s running boards. I believe they aren’t much different from 2015-2020 year either. Any ideas would be great!
